BYK-390 is a surface additive on polyacrylate basis that prevents boiling marks in baking systems and has an air-releasing effect. BYK-390 provides benefits in applications where a smooth finish and defect-free surface is required. It allows for the release of entrapped air bubbles during curing processes, resulting in a uniform appearance without pinholes or other surface imperfections. BYK-390 enhances the leveling and flow properties of coatings, helping achieve an even, high-quality finish. Its use can improve the aesthetic quality and performance of various products.
